Im going to contribute to the list of TD4 engine issues on the first page!
Todays issue;
Missfire on idle (engine rocking) and loads of white diesel smoke.
Engine doesn't hunt and no engine management light.
Engine seems to fire on all 4 above 1500rpm but lacking power.
I have been searching around the forum and seen the fuel rail pressure sensor mentioned - I tried unplugging and running the engine - it was worse when it was unplugged as the engine started hunting and the management light illuminated.
I previously had a no-start condition around 6 months ago - this turned out to be down to an injector with excessive leak-back, I replaced with a used injector with the same part number and code.
I also replaced the low-pressure fuel pump and filter at this time.
I have tried a few other things tonight - another leakdown test, which was inconclusive as all injectors seemed to leak back similar amounts.
Also checked all boost hoses and vac lines as well as cleaning the crankcase breather.
I'm thinking I possibly have a poorly injector - so my next step is to pull all the injectors and send them away to diesel bob for an overhaul.
Just wondering if there is anything else worth checking before I send the injectors away?
